“daisy-chain” the amplifier output to the next speaker. Important: please ensure that the total impedance of multiple LE Series monitors connected in this way is not less than the minimum load impedance the amplifier channel can drive: No. -
Page 8: Le200 Only - Crossover Modes
LE100/LE200 USER GUIDE LE200 ONLY – CROSSOVER MODES The LE200 may be bi-amped if wished. Configuration data for external electronic crossovers or system controllers can be found at “Speaker Parameters”).

Page 12: Mounting Options
USER GUIDE MOUNTING OPTIONS As wedge monitors, LE Series monitors will most often be used as free-standing cabinets in “landscape orientation” at floor level. The enclosures are fitted with moulded rubber feet on the base which protect the stage and help the units to retain their position. - Page 13 LE100/LE200 USER GUIDE It can be seen from the the views above that the coaxial driver is not symmetrical. For correct performance, the driver should always be orientated as shown, with the “butterfly wings” of the HF driver assembly biased towards the bottom of the enclosure. To rotate the driver, proceed as follows: 1.

Page 14: Grille Removal And Replacement
USER GUIDE Grille removal and replacement Grilles on LE Series monitors are designed to be easy to remove to facilitate driver rotation. No screws are used to hold them in place; they are manufactured with a natural spring which holds them in place in slots in each side of the cabinets. - Page 15 LE100/LE200 USER GUIDE Now lift the handle up; this will ease the grille forward slightly to prevent the return on the grille dropping straight back into the slot: Repeat this process for the remaining gaps in the grille to ease it out of the slot all the way up one side of the cabinet;...

Page 16: Badge Rotation
USER GUIDE Badge rotation The Martin Audio badge is spring loaded and can be rotated through 180 degrees to maintain a professional appearance. To do so, remove the grille and push the badge forward from the rear while turning it to the desired orientation. Once complete, refit the grille. -
